I knew you could move the accounts bar to either side of the screen. I use the accounts bar, so I wasn't aware you could hide it entirely. In their review of what's new in Q2006 brings up this very subject. So I assumed the "hide" part was new. What's really new, as I said in my original post, is that you can press F11 and have your register expand to fill the entire Quioken window. This does produce a little tab at the top of the window that can restore the window, or you can toggle F11 to restore it.
And you're right, QP2006 uninstalls QP2005. I do have a Ghost image that has QP2005 still installed, but really, do I want to go to all that trouble to verify something so trivial? I'll take your word for it.
